KW HAS, H&R Sport or Eibach Springs?

[lukehahlbohm]

I had the HAS kit and it was great. Make sure you run a 255 tire or thinner up front. I ran a 275 and tag motorsports had to adjust it to where 2-3 inches of visible wheel gap was showing.

I don't believe progressive work well in a car designed for linear springs. You cannot change the spring rate to that precise a degree, and when the car is on undulating roads the springs will be compressing and decompressing at rates that do not mesh with the oem dampers. Too soft at the top end, overextending the dampers. And again, I cannot over stress the idea of running a progressive rate on a shock designed for a linear spring does not make much sense in terms of a performance application.

Also, kw has is designed around the idea that it has adjustable perches. Meaning the level of drop can be varied by an inch or so. The progressive springs cannot be well calibrated for all different ride heights, that makes no sense. Only one ride height could be idealized with the chosen rate (which isn't even ideal in the first place imo). So you have a random progressive spring rate yet the car can be lowered anywhere from half an inch to an inch and a half? How could you possibly have ideal spring rates for all those ranges? You can't.

What did you go with at the end?
